冀东地区全株玉米青贮饲料品质研究

为探索冀东地区不同青贮玉米品种之间饲料品质的差异,本试验以冀东地区种植面积较大的4个青贮玉米品种为试材,研究比较了其在全株生物量、干物质量、全株含水量、粗蛋白质、粗脂肪、中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)含量上的差异.结果表明:4个青贮玉米的粗脂肪含量差异不显著(P>0.05);君辉521在全株生物量、干物...

Research the quality on whole-plant corn silage in Jidong area

In order to explore the difference in feed quality of silage corn in Jidong area,four silage corn varieties with larger planting areas in Jidong area were used as experimental materials.Compared the differences in the whole plant biomass,dry matter quality,whole plant water content,crude protein,crude fat,neutral detergent fiber(NDF)and acid detergent fiber(ADF)content of the four corn.The results showed that there was no significant differences in crude fat content among the four silages.Junhui 521 had the largest plant biomass,dry matter mass and crude protein content,which were 62.12,18.32 t/hm²and 93.32 g/kg respectively.The NDF and ADF values of Dongdan 1331 were the lowest,which were 332.64 g/kg and 123.21 g/kg respectively.The RFV classification of silage were special grade.In GI classification,Junhui 521 was grade 3 and the rest was grade 2.In summary,the biomass of Junhui 521 silage was higher than the other varieties,but Dongdan 1331 had better taste and nutrition was easier absorbed.
